What is the Slope of 7x+4y=20

yKpoI14uk [10]

<u><em>Answer:</em></u>

slope = $\frac{-7}{4}$

<u><em>Explanation:</em></u>

<u>The general form of the linear line is:</u>

y = mx + c

where:

m is the slope

c is the y-intercept

<u>The given equation is:</u>

7x + 4y = 20

<u>We will start by putting the equation in the general form:</u>

7x + 4y = 20

4y = -7x + 20

$\frac{4y}{4} = \frac{-7x}{4} + \frac{20}{4}$

y = $\frac{-7}{4} x + 5$

<u>Now, comparing our equation with the general form, we would find that:</u>

m = slope = $\frac{-7}{4}$

c = y-intercept = 5

Hope this helps :)

Find equations of the line that is parallel to the z-axis and passes through the midpoint between the two points (0, −3, 7) and

tia_tia [17]

Answer:

$\vec{r}(t)=\left$

In parametric form:

$x=-1, y=\displaystyle\frac{1}{2}, z=4+t$

Step-by-step explanation:

We first find the mid point:

$\displaystyle\left(\frac{0+(-2)}{2},\frac{-3+4}{2},\frac{7+1}{2}\right)=\left(-1,\frac{1}{2},4\right)$

Then, a vector parallel to the z-axis is:

$\vec{v}=\left< 0,0,1 \right>$

Then remember the equation of a line passing through point $(x_o,y_o,z_o)$ and parallel to the vector $\vec{v}=\left$ is:

$\vec{r}(t)=\left+t\left$

So, in this problem we get:

$\vec{r}(t)=\left+t\left$

After combining the two vectors:

$\vec{r}(t)=\left$

In parametric form:

$x=-1, y=\displaystyle\frac{1}{2}, z=4+t$

A farmer sells carrots and squash. A customer buys 1 pound of carrots and 1.5 ponds of squash for $7.00. Another customer buys 4

Otrada [13]

Answer:

$1.75

Step-by-step explanation:

1 pound of carrot and 1.5 pounds of squash cost $7.00.

1c + 1.5s = 7 ----------------- [ 1 ]

4.5 pounds of carrot and 1.75 pound of squash cost $14.00.

4.5c + 1.75s = 14 ----------------- [ 2 ]

<u>[ 1 ] x 4.5:</u>

4.5c + 6.75s = 31.5 ----------------- [ 1a ]

<u>[1a] - [2]:</u>

5s = 17.5

s = $3.50

<u>Sub s = 3.5 into [ 1 ]:</u>

1c + 1.5 (3.5) = 7

1c + 5.25 = 7

1c = $1.75
